Give them time JR. They are not there just to answer you. Also bear in mind that there is a local council involved in this and they are often not the most switched on as far as aviation matters go. Closing a few roads (as you have indicated) is what they know, aviation stuff is a bit of a mystery to them.
You may also find the HARS people are still on their way home from Avalon.
There is still plenty of time to disseminate any relevant operational information.
